Re: No dongle -- no exception

I just tested it and this is normal. However, the exception is still thrown but caught by the python program so that it is not visible to the user. Specifically, radiodriver.py line 204 tries to create a Crazyradio object and returns an empty list in case of an failure. I used the following "tr...

Re: [Video] Alternative Kinect Control (using depth images)

On github there seems to be a launch file named pid.launch in the launch subfolder of the package. Can you check if you have that on your local file system as well?

Re: How to create a new controller for the crazyflie?

It uses the official Leap Motion SDK to read the data from leap motion (see http://wiki.bitcraze.se/projects:crazyf ... leapmotion). I didn't look into Bitcraze code into much detail, but it would surprise me if pygame is required just for accessing the leap motion controller.

Re: Stable Flight

Instead of illumination you might be better of with IR photo receptors (and IR LEDs) to avoid issues with ambient light. Another option would be to use a Wii-mote style tracking. If you want to get fancier you can check the various posts in this forum where people used Depth sensors (like Kinect or ...

Re: Help with simple code

Please put the code within the code-environment next time.

The issue is that you are calling send_setpoint within the connected callback. Instead, execute the ramping code in another thread (and start the thread once you are connected).

Re: crazyflie for my big quadcopter

Looks nice! To reduce vibrations you might not want to strip it down directly to the frame, but but some softer foam in between. Keep us posted when it's flying!

Re: How to create a new controller for the crazyflie?

The control messages are send using pyusb. Pygame is used for the joystick support (at least on Windows and Mac; Linux seems to have a custom implementation) and I believe the widget which shows you the current orientation of the crazyflie is done using pygame as well.

Re: [Video] Alternative Kinect Control (using depth images)

Did you source your workspace correctly, i.e.

Code: Select all

source devel/setup.bash
? It sounds like it doesn't find the package.

Re: Crazyradio in PRX mode

If you just need the crazyradio driver you are good to go and it should work with python 3.x out of the box (possibly with python 2.7.x as well, but this is not tested). If you need more from the Bitcraze stack it won't work that easily because the SDK does not work with python 3.x yet. In that case...
